TL;DR
This paper demonstrates a space-like antibunching experiment with heralded single photons, showing that detector clicks are spacelike separated events, addressing foundational questions in quantum theory.
Contribution
It presents the first implementation of a space-like antibunching experiment using heralded single photons, confirming quantum nonlocality in a relativistic context.
Findings
Detector clicks are spacelike separated events.
Supports quantum nonlocality in relativistic settings.
Addresses Einstein's concerns about quantum theory.
Abstract
We use heralded single photons to perform an antibunching experiment in which the clicks at the detectors are spacelike separated events. The idea of such experiment dates back to the 5th Solvay conference, when it was proposed by Einstein as an expression of his concerns about quantum theory.
